Earlier this year, a first-time academic author published a new mathematical study in the journal Research in Number Theory. The twist? The researcher, Christopher Havens, is also serving a 25-year ...

What if Pi Day, perhaps the best known mathematical holiday, was actually better celebrated in the summer? Currently falling on March 14 — 3/14, in honor of the first three digits of the infamous ...

The proof resolves a nearly 80-year-old problem known as the Duffin-Schaeffer conjecture. In doing so, it provides a final answer to a question that has preoccupied mathematicians since ancient times: ...
